FEEDING MECHANISM FOR SEWING-MACHINES.

Application filed August 4, 1902. Serial No. 118,236.

To all whom it may concern:

Be it known that I, Josnrn BERGER, Jr., a

citizen of the United States, residing in Utica, county of Oneida, and State of New York, have invented a new and useful Improvement in Feeding Mechanism for Sewing-Machines, of which the following is a description. My invention relates to sewing machines of the type in which the binding and sewing are done simultaneously. Particularly, my invention relates to mechanism by which binding may bc-applied to all kinds of material, whether woven, knitted or otherwise produced, and in which the material and binding maybe advanced to and fed from the stitch-forming mechanism simultaneously, evenly and without puckering or stretching the one relatively to the other.

My invention has been found specially useful in binding knit goods or loosely woven fabric, because such materials have a tendency to stretch excessively under the action of the feed andduring the application of the binding, the latter being, usually,

of close weave or texture and not so liable to stretch. With these conditions of the .work it has been difficult to mechanically apply the binding evenly and smoothly and overcome the tendency of the material and binding to pucker relatively and produce unsightly work.

One of the objects of my invention is to provide a mechanism by which bindings may be applied to all kinds of fabric, with great facility, rapidity, accuracy and neatness; and by which the tendency of the material and binding to pucker relatively is overcome and prevented.

Another object of my invention is to provide means for controlling the condition of the material and binding as they are being fed to the stitch-forming mechanism; that is to say, operating upon the two, or manipulating them. in such manner as to produce precisely the condition desired at the stitch making point, thus rendering it possible for the operator to produce and maintain evenness of work during the rapid operation. of the machine.

It is a further object of my lQVOTltlOn to so enlarge the scope and OPOI'fllJlOTl' of machines of the character stated as to enable thenrto perfornu under the control of the operator, ceitain kinds of Work, such as full 7 Specification of Letters Patent.

ing one piece of work on or relatively to air other, or stretching one piece of work on or relatively to another. Also to produce a combination of stitch-forming, feeding and resser-foot mechanisms which is capable of producing the results stated.

Other objects will be set forth in the body of the description.

My invention consists in the parts, features and combinations herein described and claimed and upon which I have endeavored to lay stress by particular reference.

The essential features of my machine, combination or mechanism embrace a stitchforniing mechanism of any desirable character, a feeding mechanism involving the principles and having the features hereafter specified, and a prcsser-foot mechanism capable of performing the functionsand of being manipulated as presently .described. In some instances a binding guide of suitable conventional form may be properly 19 cated with respect to the stitch-forming, feeding and presser-foot mechanisms.

In the drawings I have illustrated a chain-stitch machine having the several features noted and portraying my invention in a form capable of attaining good results, and therein:

Figure 1 is a perspective view of a machine having my invention applied thereto; Fig. 2 is a plan view of a detail showing the feeding mechanism; Fig. 3 is a sectional elevation on the line of Fig; 2; Fig. 4

is a similar view on the line mm Fig. 2;.

Fig. 5 is a view similar to Fig. 3 showing another form of my feeding mechanism; Fig. 6 is a side elevation of the presser-foot; Fig. 7 is a vertical \section of the presserfoot on the line 11-41 of Fig. 6; Fig. 8 is a plan of a section of the throat-plate, showing a certain arrangement of the feed-dogs; Fig. 8 is a similar View showing another arrangement of the feed-dogs also showing in dotted lines the relative arrangement of the binder to these feed dogs, and the binding strip and body fabric; Fig. 9'is a rear elevation of the overhanging arm and head of the machine, showing. the presser-foot lifting means; and FigQlO is a plan showing the binding guide and tension.

The overhanging arm of the machine is indicated by A; and B, is the bed-plate; C, the work-plate;. I), the needle actuating lever; D, the needle-bar; cl, the needle; E,

the driving-wheel on the main-shaft; A, the usual spring controlled p'resser-bar; H, the presser-foot foot to the bar; and G, the throat-plate.

The resser-foot is shown as composed of the main part H, having three, parallel,

vertical bores extending from the bottom upwardly, and the central one of which extends through the top of the part H, by a narrowed or confined extension.- The part H, also carries a foot-portion 12, which may be integral therewith or secured thereto in any suitable manner. A second foot-portion 13, not so extensive as the portion 12, is provided with vertical pins 13 13 and 13, seated and sliding freely in respective 'bores of the main part H, and the central one 13, being longer than the others and operating in the extension of the central here. This central pin is surrounded by a coiled spring 14:, housed in the enlarged portion of the central bore, and said pin, at its upper end, is notched, grooved or cut away so as to provide a seat, between,

yielding pressure when the said foot is alone pressing upon the work. When the foot 13,

is forced, against the spring, to its highest extent, the screw or pin13, constitutes a stop producing a condition which renders all the parts of the foot rigid and prac tically solid. The two end pins'13 act as guides to prevent the foot 13, from turning relatively to the foot 12, and keep the two in proper relation laterally. A lever 15, pivoted to the arm A, is operatively connected with the presser-bar so as to lift the latter during the operation of the machine, any means desirable being provided for actuating the lever, such as a treadle 15 having connection 15 with said lever. It will thus be seen that, during the operation of the machine, the presser-foot can be raised or lowered at will to any desired extent.

A suitable form of binding-guide is shown in Figs. 1 and 10, the same being suitably secured to the cloth-plate by a screw and extended toya position just in advance of and beside the supplemental foot 13. The guide consists of a base-plate 16, a turning or folding guide 17, for the binding-strip 18, and a tension device for the strip 18,

comprising a rigid piece 19, a spring-strip 20, bearing thereon, a slotted holding piece 22, for confining the bent end 2-1, of the strip 20, and an adjusting-screw 23, passing through the holding piece 22, and pressing upon the strip 20, to regulate the pressure thereof on the binding strip 18. Being lb, the screw for holding the.

secured by a screw, by loosening the latter the binding-guide may be swung aside for free access to the stitching mechanism and for properly inserting the binding strip therein. This binding guide 17 is of the type known as an English hinder, the delivery end being formed at an angle to the line of feed, the material being fed into the binder at right angles to the direction of feed and by the angular form of the delivery end a reverse fold is given the binding as it leaves the hinder, the delivery end being located alongside the front presser portion of the presser foot, and in front of the rear portion of said foot.

The feeding mechanism devised for cooperating with the stitclrforming mechanism, the presser-foot and binding guide, is so constructed as to feed the body fabric or material fast or slow relatively to the feed of the binding material, or to feed the binding material fast or slow relatively to the body-material, this depending entirely upon the character of the materials operated upon or the particular effect desired.

One form of my invention is shown in Figs. 2, 3 and 4-, in which ll, isthe rockingframe, pivoted to the bed-plate B, of the machine, such frame deriving its movements through anysuitable connection with the driving shaft. The feed-bar 1*", horizontally disposed, is pivoted, or journaled at its rear end to the upper end of the rocking frame, at a, and at its forward end said bar has suitably secured thereto a feed-dog F the horizontal portion of which is pro vided with teeth, as usual. On its under side, the feed-bar is provided with an 'an gular piece between which and the body of the bar an actuating eccentric or cam on the driving shaft is embraced for imparting vertical movements. Between its ends, the rockingframe has secured thereto, in any suitable manner, a braclnet-picce cal-11ving a vertically disposed bar 1, provided with a number of perforations '1, for the reception of a screw carried by one end of an adjustable link 7, having its opposite end adjustably secured in like manner in any one of a series of perforations 2, in a similar bar 2, suitably secured to a second feedbar 1-), supported and guided in bearings 1, carried by the main feed-bar F. The second feed-bar is free to slide longitudinally on the main fecdbar and independently thereof, but is confined by its guides so as to partake of the vertical movements of the feed-bar F; the second bar, at its forward end, carries a feed-dog 6, having on its horizontal portion teeth 5. The link 7, forms the driving connection between the rocking-frame F, and the second bar 3, and as said link is adjustable 011 the. bars 1 and 2, the amount of movement transmitted from the rocking frame to the messes second feed-bar can be regulated and varied according to the character of work to be performed or the results desired. Ubviously, the movement of the second dog can be caused to feed fast or slow according to the position of the link 7 along the bars 1 and 2, and thatsaid movement may be in excess of the movement of the feed-bar F, by placingthe link 7, above the pivotal connection of the rocking-frame with thebar F as shown in Fig. 4, or may be the same as, or as much less than, the movement of said bar F, as desired, by adjusting said link 7 along said bars 1 and 2,-see ig. 3.

Another form of my invention is shown in Fig. 5, in which the second bar 3, is secured to the main-bar F, on the opposite side of the latter, by means of screws 3, passing through long slots in the second bar and by which means the latter is guided in its movements on and is secured to the bar F. .The dog 5, in this form of my invention is made integral with the second bar 3. The actuating means in this form of my invention consists of a lever 2, extending above the main feed-bar, and longitudinally slotted, pivoted at 9, to a lug 9, carried by the bed-plate, said-lever 2, being pivoted to the second bar 3, by means of a screw 11, entering the same after passing through the slot in lever 2. Motion is im rted to the lever2, by means of a link i pivotally connected at one end to the upper end of the rocking-frame F, and at its other end pivotally and adjustably connected to the lever 2, by means of a screw 10, passing through the end of link 7, and entering the slot in lever 2. By this connection it will be clear that the second feed-bar may be caused to move faster than the bar- F, or move with the same or lesser speed, according to the adjustment of the link 7, in the slot of lever 2. i

i It will be clear from the above description that the speed of the two feed-dog's may be changed relatively, and that the dog 5 may be caused to move faster or slower than the dog 7", this depending upon the character of the work to be performed, or the results desired, or the necessities of the conditions caused by the character of the work operated upon. Moreover, it will be clear that as the link 7, is moved down the bars 1, 2, the dog 5, if bar 2, is secured thereto at a right-angle, will be maintained in the same position relatively to the needle. This'is not always desirable and is undesirable in certain conditions and in operating upon certain kinds of work, such' as in needle as possible.

feeding edgings of open-work character, or in bar stitching, when it becomes necessary to'have the feed-dog operate closely to the To provide for this, the bar 2, may be secured to the second feedbar 3, at anrinclination, or obtuse angle,

in which case as the link is lowered along the bars 1 and 2, the dog 5, will be moved toward the needle, as clearly shown'in Fig. 4, thus enabling said dog to work close to the needle and engage the edging and adm vance the same with certaint The feed-dogs may be of any desired shape and size and may have any desired relation to each other, such shape and relation depending entirely upon the character 7 of work operated upon or the results or effects desired. In Fig. 8, the main-dog 24',

is shown broad and extending to the outer edge of the supplemental dog 25, the latter being narrow and lying in front of the main g dog. In Fig. 8 the dog 7'', is shown narrow and long, and the dog 5, much shorter than the dog f and lying in a plane parallel with the latter but in front thereof. The

feed dogs when arranged as shown in this 5 binder, the auxiliary feed dog 7' may be moved faster than the main feed dog 5 and 7 caused to full the elastic material sufliciently to prevent any undue stretching thereof. Inasmuch as this feed dog has a surface in engagement with the fabric during the loo feeding movement, which extends from a point substantially in a line at right angles to the feed and passing through the path of the needle to a point in advance of the needle, the body material is gathered and held in gathered position until it is caught and stitched to the binding by the stitching mechanism.

Then again, this locating of the binder directly in front of the stitching mechanism permits the stitching of the binding on to a curved edge, as the fabric can be readlly turned.

and alongside of the auxiliary feed dog 7,

The particular shapes and arrangements herein shown are merely illustrative 'of modes of carrying out the spirit of my invention and are not intended, in any sense, as limitations; for it will be clear that many changes in shapes and arrangement of parts can be made without departing from the principles of my invention.

From the above description and the illustrations afforded by the drawings, it will be clear that adjustments may be made to cause the forward dog to feed either faster or slower than the rear dog; or the latter may be given a speed of travel the same as the forward dog or faster or slower than the latter. The relative speed of the dogs dewhich operates on the'binding strip 90 in rear of the needle, and it is pends upon the character of work operated upon; and this is true also of the size and shape of the dogs and the relative disposi tien thereof. For example, in binding a garment, or sewing edging to fabric, around curved edges, it is important to feed the binding or edging faster than the garment or fabric so as to produce neat, smooth work and avoid puckering the one relatively to the other. Moreover, after the speed of the two feed-bars has been adjusted relatively, with e. g. the main bar moving faster than the auxiliary bar, it may be necessary or ing under foot 18, because the action of the .feed thereunder receives cooperation from when the feed of both dogs is the same, the

foot 12 being raised resulting in retarding the movement of the work operated upon by the dog thereunder.

\ One or more needles and complcmental stitch forming mechanisms may be used in connection with the feeding mechanism of my invention.

Another use of my invention is'in fnlling or shirring one piece of work on or relatively to another, this being accon'lplished by feeding the piece to be fulled or shirred faster than the other; or one piece of work may be stretched. on. or relatively to the other by causing one feed to move slower than the other. In fact. there is no end to the variety and character of eii'ccts and results that can be produced by regulating the speed of the feed-dogs relatively and properly manipulating the presser-fcet.

For the sake of clcarness in terminology and for convenience. denominate in "the claims the forward feed dog, or that which engages the goods in advance of the needle. as the auxiliaryfeed dog, and the rear-feed dog, or that which engages the goods and feeds them away after the stitching has been This may become important performed, as the main feed dog, andrall the respective supporting bars therefor auxiliary and main feed bars.
